When a scenario has run, the right-hand side of the Scenarios page holds its results. All local markets shows every market at once, as a map or a table; Selected local market shows one in detail. Set your risk thresholds and Sloc colours and filters the markets by them, so you can go straight to the ones that matter.

Filter by risk

The buttons above the map split the markets by how they rate, and each says how many fall into it. Click one to show only those markets; click it again to clear it. Until you tick a metric in Metrics & risk the split is simply Overlap and No overlap.

• High / Medium / Low risk - markets rated against the thresholds you set. Rating them is covered in how to rate local markets by risk with Metrics & risk.

• Low delta - markets where the merger adds less than your delta threshold, whatever the combined figure. Usually the ones the parties already led.

• No overlap - markets where only one party is present, so there's nothing to add.

The map

Every market is a pin at the site it's centred on, coloured by its risk. Click one and its catchment is drawn on the map with a card of its figures - the fascia, the catchment used, how close the nearest overlapping site is, and each metric before and after the merger. View selected local market opens it in full.

The tools down the left zoom, fit every market on screen, switch the basemap between street and satellite, search the map, and cluster or un-cluster the pins where they sit on top of each other.

The Parties legend in the corner turns the acquirer's or the target's markets off, which is the quickest way to see one side's estate on its own.

The table

Switch to Table for the same markets as rows: the market, its overall risk, the fascia it's centred on and whether that site belongs to the acquirer or a target, then the address and the catchment it was given.

Every column has a filter, and filtering here also filters the map, so you can narrow to one fascia or one town and switch back to see where those markets are. Clear all filters puts everything back.

Scroll right and each metric you've ticked has its own columns - the figure before the merger, the figure after, and the change. This is the view to use when you want the numbers rather than the geography, and it's what the download is built from.

Pro tips

• Set your thresholds before you read anything. They're what turns 35 markets into the handful worth arguing about.

• Sort the table by a metric's delta rather than its post-merger figure. A market that was already concentrated is a weaker story than one the merger changes.

• The filters and the map stay in step, so filter in the table, then switch to the map to see whether the problem markets cluster in one place.

• Click into a market for its sites, shares and catchment - see exploring the selected local market view.
